New item for the "Known Apps" section of OSMOCOM rtl-sdr
by Thomas Frisch 03 Mar '13

03 Mar '13

Hello osmocom-sdr-Team, i spent some time to get familiar with GNU-Radio and RTL-SDR stuff and have implemented an decoder for the FS20 wireless home automation protocol. Maybe this is something for the "Known Apps" section in the OSMOCOM rtl-sdr wiki. Since i am a hardware/FPGA/RF guy, my programming skills are not the best, not at all in python, so i hope the code is not too scary. Name: rtl_sdr_FS20_decoder Type: gnuradio app Author: Thomas Frisch URL: https://github.com/eT0M/rtl_sdr_FS20_decoder.git My compliments to the whole OSMOCOM Team, you are doing a great job. regards Thomas

[ANNOUNCE] OsmoDevCon 2013-04-04 till 2013-04-07, Berlin
by Harald Welte 26 Feb '13

26 Feb '13

Dear fellow Osmcoom developers, it is my pleasure to finally announce the date + venue of OsmoDevCon 2013: Date: April 04 through April 07, 2013 Place: IN-Berlin, Lehrter Str. 53, Berlin Like last year, this is an event for developers of the various Osmocom proejects. Reservation and confirmation of reservation is required. The event is free of charge. The Room is made available by IN-Berlin e.V., an Internet related non-profit organization. Lunch catering will be sponsored (so far by sysmocom GmbH, but if any other sponsors come up, we are happy to share the cost). So all you have to cover is your own travel + accomodation costs, as well as breakfast and dinner. If you are an active developer and cannot afford travel/accomodation, please let me know and I'll see if we can do something about it. If you would like to attend, please send a message to laforge(a)gnumonks.org applying for registration of the event. The registration deadline is March 5, i.e. one week from now. There is no detailed schedule of talks yet. I will start a separate discussion suggesting / collecting topics in the next couple of days. More information is (and will be made) available at http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2013 Further discussion regarding the event should be directed at the osmocom-event-orga(a)lists.osmocom.org mailing list, to avoid cross-posting over the various project-specific lists.

It behaves in the same way on Linux and Windows The Problem: The constant observation of the spike on the tuned frequency in the ranges after 160MHz or so. Is it known issue or a HW defect? If it is in the software, please let me know any possible fix. The screen snapshot and USB information are attached. $ rtl_eeprom Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Found Fitipower FC0013 tuner Current configuration: __________________________________________ Vendor ID: 0x0bda Product ID: 0x2838 Manufacturer: Realtek Product: RTL2838UHIDIR Serial number: 00000001 Serial number enabled: no IR endpoint enabled: yes Remote wakeup enabled: no __________________________________________ 73 Mikhail

rtl_fm scanning
by Ben Moore 24 Feb '13

24 Feb '13

I am having a problem with using multiple frequencies with rtl_fm. Single frequencies work just fine. For example: rtl_fm -f 462.5625M -f 462.5725M -N -s 12k -r 12k -g 48 -l 50 | play -r 12k -e signed-integer -b 16 -t raw -c 1 -V1 - Will get to: Sampling at 1008000 Hz. Output at 12000 Hz. Exact sample rate is: 1008000.009613 Hz Tuner gain set to 48.00 dB. Then freeze. If I set the squelch low enough, it will continuously monitor the first channel. If I have a transmitter on before starting the command, it will monitor that. But when the transmitter turns off, rtl_fm hangs. I looked at the code but couldn't fix it. Maybe it's some reset command that's not being done between frequencies. If I force "data_ready" to unlock, it scans, but there's no data. Although, rtl_tcp works just fine when connecting with SDR# and changing frequencies. This is on a Raspberry Pi btw, latest rtl-sdr source code. Sorry if this has already been discussed somewhere, I could not find it. - Ben

rtlsdr-based spectrum analyzer on a Beaglebone
by Alexandru Csete 19 Feb '13

19 Feb '13

Greetings, It is my pleasure to share with you a small, fun project I made few weeks ago: an rtlsdr-based spectrum analyzer running on a Beaglebone with an LCD3 touch screen. Video demo: http://www.youtube.com/watch?v=jzmFXreuFR4 Howto guide: http://www.oz9aec.net/index.php/beaglebone/480-rtlizer I also took the opportunity to start collecting bitbake recipes to create sdr oriented linux images for embedded devices. It is available here: https://github.com/csete/nanosdr I don't intend to create full blown PC-like desktops, instead I want to have fast, minimalistic linux images that can run a single GUI app without any display or window management. Think of it as a radio or an instrument that happens to run linux :) Alex
